Inside nFOX

What is Blockhouse?

Some say AI sandbox. Others say AI supermax. Blockhouse is our security fortress running inside nFOX.

Think of Blockhouse as a box that you put the AI into.

We strip AI of its privileges. Your team controls what it can access, where it can connect, and what it can do.

AI Problems

Real Problems Solved

01 Can I safely run AI on my own infrastructure?

nFOX is designed for that. It runs on hosts you control, contains workloads within Blockhouse, and records evidence for review.

02 I want to run AI on my financial data.

Your financial data stays in-house. You control the models, the access, and every step of the deployment.

03 Token costs are getting out of hand.

You don’t need a frontier model to solve most enterprise problems. Small, targeted AI can reduce token costs by orders of magnitude.

04 I’m looking for a competitive advantage.

Competitive advantage begins and ends with privacy. The real advantage? Your own team, equipped to solve problems with AI.

05 My team is afraid of runaway AI.

That’s the real fear. nFOX puts AI into a highly deprivileged environment and monitors it constantly.

06 We’ve experimented, but haven’t seen results yet.

nFOX Lab is here to help. We understand what you’re trying to do: make real, tangible gains in a real-world enterprise environment.
